Application filed July 12,

To all whom it may concern: a

.Be it known that I, CHARLES L. BRALEY,

a citizen of the United States, residing at This invention relates to improvements in- First, to provide an improved laundry drier by means of which laundry ma be quickly dried and treated with cold esh alr.

Second, to provide an improved laundry drier which is of very large capacity and at the same time simpleand economical in structure and in" use.

Further objects, and objects relating to structural details will definitely appear rom the detailed description to follow.

. I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims. A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, part of this specification, in which: v

Fig. I is a." side elevation of my im-' proved laundry drier, the casing for the air heating coil being shown partially in vertical section, other parts being partially broken away for convenience in illustration.

Fig. II is a plan View, the air inlet pipes and steam pipes .being partially broken away;

In the drawing, similar reference tars refer to simllar parts. In the drawing, I provide a'drying chamher 1, preferably the shape of an inverted characcone, or expanding upwardly. This cham berhas a conical top 2 with the central opening 3 therein provided with a grid or screen 4. The chamber has a side door 5 for the introduction and removal of laundry. At

- the botom of the chamber 1 is a central openmg provided with a screened closure 6. A blower 7 isconnected with this central opening by the pipe 8 so that air is discharged upwardly through the chamber and through the articles therein and out the top opening 3.

Iprovide an air heating means which in the structure illustrated consists of the easing 8 having the coil 9 therein. Baflles 10 forming a 1920. Serial No. 395,787.

are arranged between the loops of the coil so that theair takes a circuitous or zig-zag course through the casing-and in close contact with the loops of coils.- The steam connections are indicated 'atll. I provide an air inlet connection12 for the casing controlled by the valve 13.. The casing is connected with the blower by the pipe 14;- controlled by the damper or valve 15.

- A by-pa'ss pipe 16 connects theinlet pipe,

12 to the blower. This by-pass is provided with a valve or damper 17. Itis intended in practice that the pipe 12 shall open to the outer atmosphere or a source of pure air. By manipulating the valves heated air may be delivered by the blower and after the articles are dried cold fresh air may be admited, which aerates the articles or treats them with cold air thereby securing the result or. eflect which is secured by drying clothes in fresh open air, that clothes. so dried have a freshness which is pleasing and desirable.

The blast of air is controlled so that the articles are suspended by and agitated by the air in the. chamber which results in their even and rapid drying My improved it being well known apparatus has a very large capacity,'and

atthe same time, isvery compact as compared to its capacity and to the various dryingmeans now employed in commercial laundries.

I have not in the accompanying drawing attempted to -illustrate the parts in their relative proportions and the parts are shown more or less conventionally. I believe, however, that the disclosure made willenable those skilled in the art to which my invention relates toembody or. adapt my improvements as maybe desired or as may be necessary to the particular installation.

Having t us described my invention, what I claim as new and desire to secure by Letters'Patent, is r 1. In a laundry drier, the combination of a drying chamber having a screened inlet at the bottom and a screened discharge at the top, said chamber being tapered downwardly to its inlet, a blower connected to said inlet, an air heating means-provided with a casing connected to said blower, a heating coil within said casing, an air inlet connection f0 said heating casing, a by-pass connecting said air inlet connection with said blower, and valves arranged in said inlet connection and bypass whereby heated or unheated air may be admitted to the blower. v

2. In a laundry drier, the combination of an upwardly expanding drying chamber having a screened opening at the top and a screened inlet opening at the bottom, a blower connected to said bottom opening, an air heating means connected to said blower, a cold air connection for said blower, and valves for controlling the air delivered to the blower, so that heated or unheated air, or air tempered as may be desired, is delivered to said drying chamber.

3. In a laundry drier, the combination of an upwardly ex anding drying chamber having a screene opening at the top and a screened inlet opening at the bottom, a blower connected to said bottom opening, an air heating means provided with a casing connected to said blower, a heating coil with in'said casing, a connection from said casing to said blower, and valves arranged to control said several connections whereby heated or unheated air may be tempered as desired and delivered to said drying chamber,

4. In a laundry drier, the combination of a drying chamber having a screened inlet in the bottom and a screened discharge at the top, said chamber being tapered downwardly to its said inlet and provided with a door for charging and discharging the laundry located above and adjacent to its said inlet screen, and means for supplying a blast of air through said inlet screen.

5. In a laundry drier, the combination of a drying chamber having a screened inlet at the bottom and a screened discharge at the top, said chamber being tapered downwardly to its screened inlet, a blower connected to the inlet of said drying chamber, and means for supplying cold or heated or tempered air to the blower.

6. In a laundry drier, the combination of an upwardly expanding drying chamber having a screened discharge at the top, means for supplying a blast of air to the bottom of said chamber, whereby the articles of laundry within the drier are agitated and tumbled about within the drier by the blast of air passing therethrough.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.

CHARLES L. BRALEY.
